🧠 Scary stuff, folks. I’ve been thinking — and I’ve come to the conclusion that every single one of us has a head that’s older than their feet.
Not a metaphor. Physics.
Gravity makes time run slightly faster where the field is weaker — meaning further from Earth’s core. Your head is about 1.5 metres further from the centre than your feet. So time literally ticks faster up there.
The difference over a lifetime — around 90 nanoseconds. Sounds ridiculous. But this isn’t just theory — turns out scientists actually measured it with atomic clocks back in 2010. They put one clock on the floor, another on a table. The one on the table ran ahead.
GPS satellites account for this effect every single second. Without the correction, navigation would drift by kilometres a day.
So yeah — your head is aging faster than your feet. Just by 90 nanoseconds.
Goodnight everyone…
